To all whom it may concern:

Be it'known that I, Luoirnn J. Mos'r, a citizen of the United States, and resident of the city of New York, in the county of Queens and State of New York, have 1nvented a. certain new and useful Fountain- Pen, of which the following is a specification.

This invention relates to fountain pens, particularly tov the type known as self filling, and its principal object is to provide a simplified, inexpensive, eilicient and improved fountain pen of this type.

Other objects and advantages will hereinafter appear. In the accompanying drawings, -Fxgure -1 shows a general sectional elevation of the fountain pen. Fig. 2 is a fragmentary ele vation similar to Fig. 1, but showing the operating lever. disposed in operative state.

Fig. 3 is a sectional plan view of the fountain pen, taken on the line wac of Fig. 2.

Fig. 4 is a sectional plan view of the foun-' tain pen, taken on the line 3 -g of Fig. 1.

A flexible receptacle or sack 1 of rubber is secured to the extremity of a tube '2 fornh' ing a part of the ink-feeder 3 that carries the pen 4 with which the writing is done. The tube 2 is fittingly inserted into the extremity 5 of a tubular hard rubber holder 6, within which the entire sack 1 is thus placed and contained. WVithin the holder (land against the interior side of its wallis fixed a stamped-metal frame 7, which is provided with a projection 8 extending therefrom transversely to the axis of the holder and has a pair of wings 9 that are secured to the sides of a slot 10 formed in the wall of the holder. A bar 11 is held to the projection 8 against longitudinal shifting by means of an opening 12 thereof passing over said pro- 1 jection. Movement of the bar 11 toward the sack 1 compresses it as shown in Fig. 2, and releasing of said bar permits the sack to swell to normal-state and restore the bar to inoperative position shown in Fig. 1. An operating lever 13 is fulcruined upon'holder 6by means of journals 14 thereof passing through slotted bearing-openings 1 1 iii the ears 9. The short arm 13of said lever islocated within the ho der '6 and its extremity is lodged within a guiding slot 15 in the-bar 11, whereby upon swlnging the lever "13 in the direction of the arrow away from the holder 13 tothe position shown in Fig. 2 the arm 14 compels" the bar 11 to move and compress the sack 1, Fig. 2. When and snaps the level; 13 to closed-inoperative position within theslot10. As; said lever is snapped back its .journalsfild are located approximately at the extremity of the guiding bearing-slots 14', as shown in Fig. 2, and in orderto eii'e ct positive locking of the lever the operator may place the thumb nail againstgaledge 16 thereof and thereby shifts it longitudinally to bring a hooked projection 17 at.its reverse side to enter at the rear of a ledge 18 of the tubular holder 6,,the elongated fulcrum-slot 15 permitting'the longitudinal movement of said lever during its sliding and locking operation and a slot 7 in frame 7 permitting the projection 17 to enter beyond the ledge 18.

To unlock the lever 13- in order to operate 2, the extremity 7 of frame 7 serves to prevent sliding movement of the lever. A pin 20 secured to wings 9 serves as an abutment for the lever 13 to guide it in its longitudinal sliding operation and to prevent pressing thereof against the frame? at the bottom of slot 9. 1

After the ink in sack 1 has been cousumed the fountain pen is refilled by inserting the pen in any ordinary ink-well and simultaneously operating the lever 13 to firstsopen as in Fig. 2 and then close back into its retaining slot 10, Fig. 1. In the operation of lever 13 it-first causes the bar 11 to compress the sack and drive the air out therefrom, and then it permits said bar to release and the sack to inflate, whereupon the inkis sucked or forced up by atmospheric pressure from the ink-well, through the feeder 3, and up into the sack 1 to completely refill it. Theo aerating lever 13 may be then positively loo red at its operating extremity in the aforedescribed manner and thereby maintained securely in inoperative state until manipulation thereof is again required.

movement when the, lever is slid longitudinally.

2. A fountain pen having the combination with a flexi 1e ink receptacle, and a surrounding rigid holder therefor, of .compressing means for said receptacle, a lever for operating" said means adapted to lie against said holder when in inoperative state and being slidable longitudinally While in inoperative state, and means to positively lock said lever against opening away from the holder when it is slid longitudinally.

3. A fountain pen having the combination with aflexible ink receptacle, and a surrounding rigid holder therefor, of a bar for compressing said receptacle, a lever for operating said bar adapted to be opened awayfrom said holder and to be closed thereagainst, said lever sliding longitudinally when in closed state said lever having a projection, and said holder having a rigid portion to the rear of which said projection slides to engage it to positively lock said lever when it is slid longitudinally.

4. A fountain pen having the combination with a flexible ink receptacle, and a surrounding rigid holder therefor, of a bar for compressingsaid receptacle, a projection ex-.

tending from said holder transversely to said bar, said bar adapted to be guided by said projection against longitudinal movement during its operation, a lever for operating said bar adapted to be opened away from said holder and to be closed thereagainst, said lever being slidable longitudinally when in closed state, and means to positively lock said lever against opening away from the holder when it is slid longitudinally.

5. A fountain pen having the combination with a flexible ink receptacle, and a surrounding rigid holder therefor, of a bar for compressing said receptacle, iilever for operating said bar adapted to be opened away from said holder and to be closed thereagainst, said lever being slidable longitudinally when in closed state, a pin secured to said holder to aline said lever witlr said holder when in closed state and to guide it in its longitudinal movement, and means to positively lock said lever against opening away from the holder when it is slid longitudinally.

6. A fountain pen having the combination with a flexible ink receptacle, and a surrounding rigid holder therefor, of a bar for compressing said receptacle, a lever for operating said bar adapted to be opened away from said holder and to be closed thereagainst, said lever adapted to slide longitudinally when in closed state, said holder having an abutment to aline said lever with the holder when in closed state and to guide itin its longitudinal movement, and means to positively lock said lever against opening away from the holder when it is slid longitudinally.

7. A fountain pen having the combination with a flexible ink receptacle, and a surrounding rigid holder therefor, of a bar for compressing said receptacle, a projection extending from said 4 holder transversely to said bar, said bar adapted to be guided by said projection against longitudinal movement during operation, a lever for operating said bar adapted to be opened away from said holder and to be closed thereagainst, said lever adapted to slide longitudinally when in closed state, said holder having an abutment adaptedoto aline said lever with the holder when in closed state and to guide it in its longitudinal movement, and means to positively lock said lever against opening away from the holder when it is slid longitudinally.
